Patented June 16, 1931 UNITED. STATES MAURICE FRANQOIS MOREA'U, OF EPINO'UZE, FRANCE MECHANICALLY DRIVEN MOWING MACHINE Application filed April 2, 1927, Serial No. 180,529, and in France April 2, 1926.

In the mechanically driven mowing machines, which are now frequently used and adapted either for animal traction or for coupling at the rear of a truck, the recipro- D eating motion of the knife is due to the turning of the vehicle wheels and depends consequently on the movement of the 1now-' ing-machine.

In other ki ds of machines, the knife is driven by an independent motor mounted on the frame. V

The invention has for its object to provide a device which may be directly fastened on the truck and driven by the auxiliary or driving pulley which is'supported and supporting parts, the aforesaid device on one side of the truck and connected directly to the motor shaft, said device allow- I ing to fit directly on the other side a mowing machine comprising only the usual cutting being substituted to the driving parts.

This device, which is enclosed in a box fastened to the gear-case of the truck, comprises substantially a pulley with its shaft 25 parallel to the shaft of the existing pulley directly driven by the engine, the. first named pulley acting in combination with a level gear and transmitting directly the mo tion of the engine to the operating rod of the mowing-machine.

This device offers especially the following advantages Y (a) Use of the engine of the truck for driving (6) Elasticity of the belt drive which prevents in a great measure the fractures of the knife frequently caused by the presence of a hard strange body,

(0) Possibility, due to the site of the crank disc, to use a very long rod, realizing ings being chiefly given as indications.

Fig. 3 is an end view, the pulleys being removed,

' Fig. 4 is a perspective view showing the invention applied on a Fordson truck, Figs. 5 and 6 are respectively elevation and plan view showing how the driving parts of the mowing-machine are connected to the truck.

The ordinary pulley P of the truck which is directly connected to the motor shaft and not to the axle shaft of the t'ruckwheels, transmits its rotary motion through a belt Q to another pulley A the shaft B of which is parallel to that of the aforesaid pulley P. f

On said shaft B a level pinion C is keyed which drives at its turn a pinion D keyed on a shaft E which supports at its other end a crank disc G the'pin of which receives the head of the-rod I of the mowing-machine connected to the other side of the truck, on the left side in the drawings,

If the truck does not comprise a disengaging-gear for the pulley P, a loose pulley A inayAbe provided on the same shaft as puley Q The shaftsB and E are centered and held in position by means of an abutment K and ball-bearings L fitted in a box M arranged as oil-bath.

The box M is fastened on the truck case S by means ofa coupling plate N and a bracket 0 suitably shaped accordingto the :truck case.

What I claim as my inventionand desire to secure by Letters Patent is 2- A mowing machine attachment. fora tractor, provided with a'take-oflf pulley connected directly to themotor shaft, comprismg in combination with cutting apparatus including a finger bar and a reciprocating cutter bar, means to attach the cutting apparatus to a tractor, a box having means whereby the same may be attached to the tractor, a pair of shafts arranged at right angles to each other. and mounted in bearings with which said box is provided, said shafts being geared together and one of them being parallel with the axis of said take-off pulley and provided with a pulley, an endless band connecting said pulleys, a crank disc carried by the other shaft and a rod pivoted on the crank of said disc and pivotally connected to the cutter bar of the mowing mechanism.

In testimony whereof I aflix my'signature.
